(Cl. 2li-55) 1 Claim.

This invention relates to a storm sash and more particularly to a sash adapted for use in connection with steel easement windows.

The mounting of storm sash on easement windows has for a long period of time presented obstacles due primarily to the fact that it is of course necessary to screen the entire opening with the storm sash in order to secure any benefits from the latter. The screening of the entire area presents difliculties in that access to the easement sash for the purpose of cleaning or adjusting them is obstructed by the storm sash and as a result easement windows have not been employed as frequently as might be and their popularity has been retarded.

The primary object of the present invention is to effectively mount storm sash in easement windows and yet preserve the accessibility to the sash of such windows for the purpose of cleaning or adjustment.

Another object of the invention is to render available the benefit to be derived from storm sash to the users of easement windows and hence to avoid the objections to the latter heretofore entertained.

A further object is to effect a dust and weather proof junction between the storm sash and its supporting frame and yet allow the panels making up the storm sash to be readily removed and stored when their use is no longer desired.

The above and other objects may be attained by employing this invention which embodies among its features a storm sash frame adapted to be mounted within the frame of a easement sash and against one of the stops thereof, which storm sash frame comprises a pair of channels in parallel relation, glass panels adapted to be slidably supported in the channels in such a manner that one panel may move past the other to partially open the window, and supporting rollers upon which the lower edges of the glass panels are adapted to be sustained whereby sliding movement of the glass panels will be facilitated.

Other features include so arranging the storm sash frame that the glass panels may be removed simply by lifting them one at a time off of the supporting rollers and projecting their uppermost edges into the uppermost channel of the frame to a point where the lower edge of the glass panel may be extracted from its' position within the frame and then lowering the entire glass panel, thus clearing the window. It will be understood of course that having removed the glass panels the entire storm sash is dismantled and the panels may be stored for subsequent use without removing the storm sash frame.

In the drawings:

Figure 1 is a fragmentary horizontal sectional view through a wail and window equipped with a steel easement sash and showing my improved storm sash in position therein,

Figure 2 is a perspective view of the storm sash and frame,

Figure 3 is a transverse sectional view on an enlarged scale through one of the side bars of the storm sash,

Figure 4 is a fragmentary plan View of Figure 3, and l Figure 5 is a, view similar to Figure 3 showing the glass panels therein and resting upon rollers.

Referring to the drawings in detail a wall Ill is provided with the usual window opening I I in which a frame for a easement sash I2 is mounted in the customary manner. The frame I2 is preferably of steel and is provided with the usual stops I3 against which the easement sash Il which are hinged to the frame as at I5 abut when they are in closed position.

My improved storm sash comprises a frame designated generally IB comprising vertically extending stiles or side bars joined at opposite ends in spaced parallel relation by means of top and bottom bars and the side and end bars are formed of channel members designated generally I1, each of which is formed from a strip of spring metal preferably of a non-corrosive character such as spring brass, aluminum or other alloys possessing the desired characteristics. Each strip of material forming the side bar is bent as illustrated in Figures 3 and 5 to form a pair'of upstanding parallel walls I8 the upper portions of which are outwardly offset as at I9 and have their upper edges joined by arched portion 20 to form a central bead or divider strip which extends between the glass panels forming the storm sash when the device is assembled. Each of the walls I8 is provided at its lower edge with an outstanding flange 2| forming the bottom of its respective channel and proieeting in the general direction of the arched portion 20 are outwardly extending side fianges 22 formed at their free ends with inturned re-entrance tongues 23. In normal position when no glass is inserted in the channel, the flanges 22 converge from the bottoms 2I toward their free ends so that when a. glass panel is inserted in its respective channel theilanges or tongues 23 will be yieldingly held in close contact therewith to form a dust and through which the rollers project to form sup-v ports for glass panels 26 as illustrated in Figure 5.

The frame I'I is mounted in the framef'I-Z" against the stop I3 as il1us`trated''=inFigur-e' l-V` whereupon the glass panels 26 are inserted 'in their respective channels rst'by introducing the f upper ends of the panels into the channels to without departing from the spirit and scope of the invention as claimed.

What I claim is:

A frame structure for a storm sash which includes top, bottom and side rails joined at their ends to form a rectangular frame, each such rail comprising a pair of longitudinally spaced parallel channels, a longitudinally extending enlarged arched head yieldingly joining the edges of adjacent anges of the channels, and inturned longitudinally extending yielding tongues carried by the edges of the flanges of the channels remote from those joined by the head, said tongues cooperating withl the head in effecting a dust and .weather tight junction between the channels and glasses mounted therein, and a roller carriage mounted in each channel of the bottom rail of the frame upon which the lower edge of a glass formed in the topmost cross bar of the frame I6'.

The panels are then moved into such a position that their lower edges -align 'with the'rnouths of the channels in the lowermost 'frame member and the panels are then entered into the-space between the portions I9 and the tongues 23 so as to rest upon the upper portions of the rollers v'25.

It is to be understood of course" that the panelsv 26 are of a width slightly more than Aone-'half of the width of the frame I6 so that they may be slid sideways on the rollers 25 not only for the purpose of facilitating insertion of the glass panels but also to provide for access Ito the case-yx ment sash for the purpose of adjusting or cleaning of the latter.

While in the foregoing there has been shown' and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination, and arrangement of parts may be resorted.

rests.
